PEEP SIGHT FOR FIREARMS.

Application filed August 10, 1922. Serial No. 580,949.

To all whom it may concern:

Be it known that I, Jnssn CONRAD MAT- THEWS, a citizen of the UnitedStates, and a resident of Kamiah, in the county of Lewis and State ofIdaho, have invented certain new and useful Improvements in Peep Sightsfor Firearms, of which the following is a specification.

My invention is an improvement in peep sights for firearms.

An important object of my invention is to provide a peep sight which maybe r0- tatably adjusted for accurate aiming when firing at differentdistances.

Another important object of my inven tion is to provide a sight whichmay be attached to any firearm without changing the construction of thesame.

A further object of my invention is to provide a sight which consists ofbut few parts and yet is efiicient in operation.

The foregoing objects I accomplish by means of such structure andrelative ar rangement of parts as will more fully appear from a perusalof the following description and accompanying drawings.

In the drawings forming a part of this application and in which likenumerals are employed to designate like characters throughout the same,

Figure 1 is a perspective view of my invention showing the same in use,

Figure 2 is a front view of the sight, and

Figure 3 is a detail view of the rotatable disk.

A standard 10 is provided and carries a rotatable disk 11 by means of apin 12. The standard 10 contains a vertical slot 13 near its top, whilea fine wire 14 passes lengthwise through its center and is fastened ateach end. A depression 15 is made between the top of the vertical slot13 and the upper edge of the standard 10 and is adapted to receiveprojections for locking the rotatable disk in a predetermined position.

The rotatable disk 11 is perforated with a series of sight openings 16,17, 18, 19, 20 and 21 which vary in size and are placed at differentradial distances from the center of the disk, so that the line of sightis automatically determined for different. ranges or distances. Each ofthe sight openings, which are numbered according to their range, andhave directly opposite them a projection 27 which is adapted to enterthe depression 15 of the standard 10 and secure the opposite sightopening in alinement with the slot 13. The periphery 28 of the disk 11is serrated to facilitate the grip when the same is being rotated.

In use, the standard 10 is attached to the breech or barrel of anyordinary firearm and the disk 11 is rotated until the desired sightopening appears in the slot 13. A projection 27 will enter thedepression 15 and secure the sight opening directly in the center of theslot 13. When a different sight opening is desired the disk 11 isrotated until the desired opening appears in the center of the verticalslot 13.

By my invention it will be noticed that I provide a sight composed oftwo sections movable relative to each other, one of these sectionshaving a sight line extending radially to the axis of the gun and theother having a series of openings of different sizes spaced at differentdistances from the center of the gun and gradually increasing in sizetoward the opening which is farthest from the axis of the gun, the partsbeing so arranged that these openings may be brought successively intoregistration with the sight line of the other section of the sight.

Although I have described only one form of my invention, it is to beunderstood that various changes may be made in the construction andarrangement of parts without departing from the spirit of the inventionor the scope of the claims.

I claim A peep sight comprising a standard of substantially circularformation and having an elongated opening near its top portion, a wiresecured centrally of the opening and radially of the standard, a discrotatably mounted on the standard, said disc having apertures ofdifferent diameters arranged spirally about the face thereof, and meansfor holding the disc in a predetermined position, including a depressionon the outer cumference of the disc and in radial alinc- 1 ment with theapertures whereby to engage the depression in the standard and forsuccessively maintaining the apertures in alinement with the elongatedopening and for locating the vertical diameters of the openings inalinement with the wire.
